Te (zZZ whom 'it may concem:

Be it known that I, JonAN SIGISMUND FAsTING, a subject of the King ofDenmark, residing at Frederiksberg, near Copenhagen, Denmark, hareinvented certain n'ew and useful Improvemcnts in Pumps, of which thefollowing is a spccification, reference being had to the accompanyingdrawing, forming a part hereof.

This invention relates to means for operating pumps of the generalcharacter of that shown in Letters Patent of the United States, No.315,171, dated April 7, 1885. In pumps ot this character there is nopiston but the pump harrel i reciprocated somewhat rapidly so that. byreason of the inc'tia other fluid pumped, the pump barre] is moved morerapidly than the water or other fluid. Such pumps are particularlyadapted tor use as mud or sand pumps, but arc obviouslr capable of usefor pumping water, air-orany fluid or material which has the general'characteristic of fluidity.

In accordance with the invention the pump burrel is reciprocated rapidlyby means of an eccentrie weight mounted to rotate upon a movablc ax iswhich is connected to the pump burrel, so that the latter partakesof therapirl reciprocations or vibrations imluced by the rotation ofsucheccentric weight about the movable axis of -otation.

The invention Will be more fullyexplaiued hereinafter with reference tothe cmbodiaccompanypump barrel is reciprocated rapidly, the valve 2 ismoved from its seat clownward movement, or other relative movement, ofthe provided such movement 'of the pump barrel is more rapid of theliquid in the same influence of gravity or prcssure from any othersource, and during the upwarcl or other relative movement of the pumpbarre] the valve is closed and the liquid is moved upward or forward. Inthis nanner an upward or forward pulsating flow of the liquid or fluidthrough the valve 2 and the pump barrel 1 is obtained, and it will beobvious that the strength of the flow will depend mainly on the rapidityof the pulsations. To ctfect the desired reciprocations of the pumpbarrel, there is provided an eccentric weight 5 which is rotated rapidlyby any suitable means, as by a belt pulley G upon which theweight ismounted and a belt 7, and the arci's of rotation of the weight issupported in suitable bearings which are movable in a longitudinaldirection with the pump barrel, such movable axis or movable bearingstherefor being con- 'rccted with the pump barrcl 1 so that the latter isreciprocated with the rcciprocations of such axis or bearings which areinduced by the rapid rotation of the eccentric weight. As shown in Fig.1 the bearings 8 of the axis of rotathe pump barrel l or to an extension-thereof, with respect to the pump barrel, pump barrel itself` beingthus movably supported, pal-takes of the reciprocations of the movablebearings of the eccentric weight.

In Fig 2 the a check Valve 2 the liquid to be ciprocations by by a link9 with the bcarings 6 which carries the eccentric driven by a belt 7.

ing drawing in which` Fgrc 1 is a View in Outline, representing oneembodincnt of the invention, and Fig. 2 is a similar View, representinganother emhodiment ot' the invention. l e In the embodiment of theinvention representccl in Fg. 1 the tube or pump barrel 1 is shown ashaving near its lower end a check' valve 2 opening upward and assupported by spri'ngs 3, secured to a fixed upport 4, so that the pumpbarrel may reciprocate in. a longitudinal direction. The pump barr-el.in this case, is shown as supported in which rest upon a a verticalposition and as having its lower ciprocations of the cnrl directlyimmersed in the liquid to be of rotationof the pumpcd, but, as will beobvions, it. might be supported in any other position and might beconnected through a flexible pipe, or' otherwise, with the body ofliquid to be pumpcd. As will be understood, when the and shown asimmersed in moved, s guded n ts re- 8 of the pulley weight 5` and is Inthis case the bearings fixed support 8. The rebearings 8 or of the axisunbalanced or eccentric also the discharge shown as mounted upon thefixed support 8 and as connected with the pump barrell by longitudinallymovableand are therefore movable 'longtudinally so that the c) the axisof rotation of guides 10 and is connected,

8 are supported movably upon springs 8 I 105 during the tion of theweight are Secured directly to pump' barrel 1 provided With Weight 5-are therefore transmitted to the pump barrel through the link 9. 'Inthis case pipe 12 of the pump isg a flexible pipe 11. The discharge pipeis also shown as provided With a check valve 13 and with an air chanber14:. Obviously the check valve 2 may he located at any convenient pointand the pump burrel may be reciprocated in a right line or in a curvedline.

Various other modifieations in the construction and arrangement of theparte will readily suggest themselves and it is understood, therefore,that the invention is not restricted to the particular Construction andarrangement shown and described herein.

I claim as my invention:

l. The combination with a punp ban-el capable of longitudinalreeiprocation and a check valve therefor, of an eecent'ic rotatableWeight and bearings for the axis of rotation of the Weight novablelongitudinaliy with the pump burrel and connected there- 1 with, wherebythe pump burrel is reciprocated with the reeiprocations of said bem'-ings induced by the rotation of the eccentric weight.

2. The combination with a pump barrel eapable of Iongitndinal'ecip'rocation and a check valve therefor, of a pnlley having :neccentric weight and be 'ings fol' said pulley connected with the pumpha''ei, whereby the pump'harret 'eeiprocates with the reciproeztions ofsaid benrings indnced by the rotztion of the eccent'ic weight.

In witness whe'eof, 1 have hereunto signed mynznne in the presence oftwo subscribing witnesses.
